Bootcamp and windows driver on already partitioned disk

When you install Bootcamp and try to use it on an already partitioned hard disk, it will complain telling you that you have to have a disk with only one partition.

If you just need it to burn the windows cd driver, you don’t need to repartition you hard disk.

CTRL+Click on the Boot Camp Assistant and choose Show Package Contents. Now navigate to Contents -> Resources and you’ll find a DiskImage.dmg. Just burn that disk image and it’s all done.
